MPLS BENEFITS:
1) faster switching than IP as IP Forwarding is based on IP routing table search each address is 4 octets length and can cause some time to calculate.
2) Core free from BGP as the MPLS is based on label switching there is no need any more for core routers to participate in the BGP network and only Edge routers need to be BGP aware. This is a huge memory and utilization saving.
3) MPLS TE Traffic Engineering is one of the major benefits as it is allowing you to have better path selections and load balancing.
4) MPLS VPN is another major benefit as it is reducing manageability and introducing simplicity to the client. before if the client wanted to create a VPN for his offices network he needed to either create tunnels between all his offices creating a lot of configuration and complex design
